You're right about using Array.prototype.find to find a matching service object if one exists.

You could spread the service object and pass it as props to the Servicio component if there's a match. And you have to access the props in a class component via this.props.

QUESTION

Estimating camera angles using homography

Asked 2020-Apr-28 at 14:42

I've been trying to estimate the euler angles (Rotz(yaw)*Roty(pitch)*Rotx(roll)) of a UAV from the homography between two frames. This means that the rotation I get from each frame to the previous one has to be multiplied by the previous one to get the total rotation with respect to the initial axes. So: R_accumulated=R01*R12*... Those R are obtained from decomposeHomography() in openCV. According to REP and OpenCV homography page, the camera reference is Z forward, X rigth and Y down but my UAV reference system is ENU. The question is how to get from that R_accumulated the dron orientation.

The R_accumulated from the homography tells you how to convert one plane into another. So if I want the camera orientation, the camera have to do the opposite movement to get the same result ( inv(R_accumulated)) ? Then that camera orientation matrix should be transformed to ENU coordinates? I have tried doing this with several rotations but I do not get good results.

The best one I've had is by getting the angles directly from R_accumulated and exchanging pitch and roll. That's a very good estimation but I still need to know some kind of rotation matrix from the camera frame to the UAV one.

I don't know if you have understood me.

...

ANSWER

Answered 2020-Apr-28 at 14:42

Finally, I have the solution to my problem:

If UAV axes are different from those of the camera, we have to find a matrix R1 that transforms UAV axes into camera ones and another one that does the same task the other way around, from camera axis to UAV axis, R2.

The homography returns the value of translation and rotation that should be applied to the first PICTURE to get the second one. But we want the camera pose, not the picture one. So, for example, if the z axis is pointing at an object who has an arrow pointing upwards, a 90º rotation of the IMAGE around that forward axis will make the arrow point right. But this is not the rotation the camera has to do to get the arrow pointing right. If you want the arrow pointing right you have to rotate the camera -90º along that same axis. In conclusion, the camera movement is the inverse of the image, so the camera rotation will be the inverse of the homography rotation and the traslation will be -1*(homography_traslation) * scale_factor.

Suppose we have a rotation R between the initial image and the final one. If we want to obtain the EulerAngles(preferable called Tait-Brian) as Rotz * Roty * Rotx of the UAV, we have to calculate the EulerAngles of R1 * inv(R) * R2. That R is the multiplication of all the intermediate rotations between frames so that R = Rinit * ... * Rend

QUESTION

RDFS analogue to owl:equivalentClass?

Asked 2018-Apr-14 at 21:01

I have triples that say patient P participates in health care encounter E which has output M, a drug prescription. Prescriptions can mention a drug from the Drug Ontology, or DrOn.

In this case, let's say that M1 mentions the cholesterol-lowering medication atorvastatin, which was imported into DrOn from ChEBI as http://purl.obolibrary.org/obo/CHEBI_39548:

prefix obo: :M1 obo:IAO_0000142 obo:CHEBI_39548 .

ChEBI has an axiom that obo:CHEBI_39548 has the role http://purl.obolibrary.org/obo/CHEBI_35821, "anticholesteremic drug". That makes it easy to find patients who have been prescribed atorvastatin, or other drugs with the same role.

Unfortunately, DrOn created its own terms for some drugs instead of importing them from ChEBI. For example, another cholesterol-lowering drug, rosuvastatin, is modeled as http://purl.obolibrary.org/obo/DRON_00018679 instead of http://purl.obolibrary.org/obo/CHEBI_38545. ChEBI's term for rosuvastatin is also annotated with the role obo:CHEBI_39548, but obo:DRON_00018679 is not. So patients in my dataset who were prescribed rosuvastatin do not show up in my existing role-based query.

I have these data in a GraphDB RDFS-plus repository, and I'd prefer not to change the reasoning level right now. If it was an OWL repository, I would just say

obo:CHEBI_38545 owl:equivalentClass obo:DRON_00018679

Is there something similar I can do with RDFS, or a GraphDB custom ruleset?

If it was an OWL repository, I would just say

obo:CHEBI_38545 owl:equivalentClass obo:DRON_00018679

Is there something similar I can do with RDFS, or a GraphDB custom ruleset?

First

You obviously can replace owl:equivalentClass with two reciprocal rdfs:subClassOf. As for the very equivalence of these formulations, I suppose this is relevant:

OWL 2 Direct Semantics, Table 4;
OWL 2 RDF-Based Semantics, Table 5.8 and Table 5.9.

Second

owl:equivalentClass is already within RDFS-Plus.

From chapter 7 of the 1st edition of Semantic Web for the Working Ontologist, where RDFS-Plus was first introduced:

RDFS-Plus provides a more intuitive expression of class equivalence, using the construct owl:equivalentClass.

In GraphDB, the RDFS-Plus and RDFS-Plus (Optimized) rulesets support owl:equivalentClass. There are the following rule in the builtin_rdfsPlus-optimized.pie file:

Can GraphDB load 10 million statements with OWL reasoning?

Asked 2018-Jan-16 at 17:28

I am struggling to load most of the Drug Ontology OWL files and most of the ChEBI OWL files into GraphDB free v8.3 repository with Optimized OWL Horst reasoning on.

is this possible? Should I do something other than "be patient?"

Details:

I'm using the loadrdf offline bulk loader to populate an AWS r4.16xlarge instance with 488.0 GiB and 64 vCPUs

Over the weekend, I played around with different pool buffer sizes and found that most of these files individually load fastest with a pool buffer of 2,000 or 20,000 statements instead of the suggested 200,000. I also added -Xmx470g to the loadrdf script. Most of the OWL files would load individually in less than one hour.

Around 10 pm EDT last night, I started to load all of the files listed below simultaneously. Now it's 11 hours later, and there are still millions of statements to go. The load rate is around 70/second now. It appears that only 30% of my RAM is being used, but the CPU load is consistently around 60.

are there websites that document other people doing something of this scale?
should I be using a different reasoning configuration? I chose this configuration as it was the fastest loading OWL configuration, based on my experiments over the weekend. I think I will need to look for relationships that go beyond rdfs:subClassOf.

@MarkMiller you can take a look at the Preload tool, which is part of GraphDB 8.4.0 release. It's specially designed to handle large amount of data with constant speed. Note that it works without inference, so you'll need to load your data and then change the ruleset and reinfer the statements.

How to keep track of the amount a certain loop has run and storing values into arrays

Asked 2017-Oct-02 at 16:58

I am a newbie in coding and preparing an assignment in which I am encountering certain difficulties. I just want you guys to help me identify my mistake for one issue I am facing. Before pasting my code I am giving an overview of what had to be done. The user have to create drones and after creating one drone the program should return back to the main menu, store the details of the 1st drone and if request to enter another drone he/she should be allowed to do so until the number of drones have reached 10. Only 10 drones are allowed and we have to use arrays for storing the values of each drone. I am unable to make the program count 10 and using arrays to store them. In the code I have pasted here, I am trying for 2 but I am unable to do that as well. Please help me...

As far as I can understand you are stuck in this part.

How to continue getting input?

For that you need to write a while(1){..} with a propr exit condition like break etc.

Rest of the job boils down to how many drones are there? and accessing and storing them.

For storing an array of structure will be sufficient. For count of drone you can use a seperate variable. Accessing them is nothing but array access.
